10 syslog-ng-ctl [command] [options]
11
13 NOTE: The syslog-ng-ctl application is distributed with the system
14 logging application, and is usually part of the syslog-ng package. The
15 latest version of the syslog-ng application is available at the
16 official syslog-ng website[1].
17 This manual page is only an abstract, for the complete documentation of
19 syslog-ng, see The Administrator Guide[2].
20 The syslog-ng-ctl application is a utility that can be used to:
22 • enable/disable various syslog-ng messages for troubleshooting
24 • display statistics about the processed messages
26 • reload the configuration of .
28
30 command [options]
31 Use the syslog-ng-ctl <command> --set=on command to display verbose,
33 trace, or debug messages. If you are trying to solve configuration
34 problems, the verbose (and occasionally trace) messages are usually
35 sufficient. Debug messages are needed mostly for finding software
36 errors. After solving the problem, do not forget to turn these messages
37 off using the syslog-ng-ctl <command> --set=off. Note that enabling
38 debug messages does not enable verbose and trace messages.
39 Use syslog-ng-ctl <command> without any parameters to display whether
41 the particular type of messages are enabled or not.
42 If you need to use a non-standard control socket to access syslog-ng,
44 use the syslog-ng-ctl <command> --set=on --control=<socket> command to
45 specify the socket to use.
46 verbose
48 Print verbose messages. If syslog-ng was started with the --stderr
49 or -e option, the messages will be sent to stderr. If not
50 specified, syslog-ng will log such messages to its internal source.
51 trace
53 Print trace messages of how messages are processed. If syslog-ng
54 was started with the --stderr or -e option, the messages will be
55 sent to stderr. If not specified, syslog-ng will log such messages
56 to its internal source.
57 debug
59 Print debug messages. If syslog-ng was started with the --stderr or
60 -e option, the messages will be sent to stderr. If not specified,
61 syslog-ng will log such messages to its internal source.
62 Example:
64 syslog-ng-ctl verbose --set=on
66
68 stats [options]
69 Use the stats command to display statistics about the processed
71 messages. The stats command has the following options:
72 --control=<socket> or -c
74 Specify the socket to use to access syslog-ng. Only needed when
75 using a non-standard socket.
76 --reset or -r
78 Reset all statistics to zero, except for the stored counters. (The
79 stored counters show the number of messages stored in the message
80 queue of the destination driver, waiting to be sent to the
81 destination.)

118 command [options]
119 Use the syslog-ng-ctl reload command to reload the configuration file
